在启动tomcat的时候提示8080端口被占用,后来经过查找发现如下结论:
将Oracle与tomcat、jboss等其它占用8080端口的服务器安装在一台机器上,会出现8080端口被占用的错误。
一、首先检查8080端口的使用情况
[root@olivenan root]# lsof -i :8080 -n
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
tnslsnr 1031 oracle 12u IPv4 2013 TCP *:webcache (LISTEN)
[root@olivenan root]# lsof -i tcp:8080 -n
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
tnslsnr 1031 oracle 12u IPv4 2013 TCP *:webcache (LISTEN)
发现8080端口被oracle使用,,注意lsof命令参数的使用。
[root@olivenan root]# lsof -i udp:8080 -n
[root@olivenan root]# lsof -i|grep 8080
[root@olivenan root]# netstat -tln|grep 8080
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN
[root@olivenan root]#
二、解决方法一
查找解决方法
将*.dispatchers='(PROTOCOL=TCP) (SERVICE=orclXDB)'
修改为#*.dispatchers='(PROTOCOL=TCP) (SERVICE=orclXDB)'
[oracle@olivenan dbs]$ sqlplus "/as sysdba"
SQL*Plus: Release 9.2.0.4.0 - Production on Fri Jul 6 10:37:32 2007

Connected to:
Oracle9i Enterprise Edition Release 9.2.0.4.0 - Production

JServer Release 9.2.0.4.0 - Production
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> create spfile from pfile;
File created.
SQL> startup
ORACLE instance started.
Total System Global Area 236000356 bytes
Fixed Size 451684 bytes
Variable Size 201326592 bytes
Database Buffers 33554432 bytes
Redo Buffers 667648 bytes
Database mounted.
Database opened.
SQL> exit
[root@olivenan root]# lsof -i :8080 -n
[root@olivenan root]
结果端口8080停止被占用
三、解决方法二
将xmlDB的端口转换为其它端口,此例转换为8082
SQL> call dbms_xdb.cfg_update(updateXML(dbms_xdb.cfg_get(), '/xdbconfig/sysconfig/protocolconfig/httpconfig/http-port/text
()', 8082));
Call completed.
SQL> exec dbms_xdb.cfg_refresh;
PL/SQL procedure successfully completed.
将ftp端口由2100转换为2111
SQL> call dbms_xdb.cfg_update(updateXML(dbms_xdb.cfg_get(), '/xdbconfig/sysconfig/protocolconfig/ftpconfig/ftp-port/text
()',2111));
Call completed.
SQL> commit;
Commit complete.
SQL> exec dbms_xdb.cfg_refresh;
PL/SQL procedure successfully completed.
SQL>
SQL> select dbms_xdb.cfg_get from dual;
CFG_GET
--------------------------------------------------------------------------------
$ @serverendp.ssh admin 4321 4322 -register
$ exit
就能把原来的8080换成4321,把9090换成4322.

Oracle View Encryption allows you to encrypt data in the view, thereby enhancing the security of sensitive information. The steps include: 1) creating the master encryption key (MEk); 2) creating an encrypted view, specifying the view and MEk to be encrypted; 3) authorizing users to access the encrypted view. How encrypted views work: When a user querys for an encrypted view, Oracle uses MEk to decrypt data, ensuring that only authorized users can access readable data.

Uninstall method for Oracle installation failure: Close Oracle service, delete Oracle program files and registry keys, uninstall Oracle environment variables, and restart the computer. If the uninstall fails, you can uninstall manually using the Oracle Universal Uninstall Tool.

Deleting all data in Oracle requires the following steps: 1. Establish a connection; 2. Disable foreign key constraints; 3. Delete table data; 4. Submit transactions; 5. Enable foreign key constraints (optional). Be sure to back up the database before execution to prevent data loss.

Oracle Invalid numeric errors may be caused by data type mismatch, numeric overflow, data conversion errors, or data corruption. Troubleshooting steps include checking data types, detecting digital overflows, checking data conversions, checking data corruption, and exploring other possible solutions such as configuring the NLS_NUMERIC_CHARACTERS parameter and enabling data verification logging.

Solutions to Oracle cannot be opened include: 1. Start the database service; 2. Start the listener; 3. Check port conflicts; 4. Set environment variables correctly; 5. Make sure the firewall or antivirus software does not block the connection; 6. Check whether the server is closed; 7. Use RMAN to recover corrupt files; 8. Check whether the TNS service name is correct; 9. Check network connection; 10. Reinstall Oracle software.

Oracle database paging uses ROWNUM pseudo-columns or FETCH statements to implement: ROWNUM pseudo-columns are used to filter results by row numbers and are suitable for complex queries. The FETCH statement is used to get the specified number of first rows and is suitable for simple queries.

The method to solve the Oracle cursor closure problem includes: explicitly closing the cursor using the CLOSE statement. Declare the cursor in the FOR UPDATE clause so that it automatically closes after the scope is ended. Declare the cursor in the USING clause so that it automatically closes when the associated PL/SQL variable is closed. Use exception handling to ensure that the cursor is closed in any exception situation. Use the connection pool to automatically close the cursor. Disable automatic submission and delay cursor closing.

In Oracle, the FOR LOOP loop can create cursors dynamically. The steps are: 1. Define the cursor type; 2. Create the loop; 3. Create the cursor dynamically; 4. Execute the cursor; 5. Close the cursor. Example: A cursor can be created cycle-by-circuit to display the names and salaries of the top 10 employees.
